Optical edge detection based on high-efficiency dielectric metasurface
Junxiao Zhou,Haoliang Qian,Ching-fu Chen,Junxiang Zhao,Guangru Li,Qianyi Wu,Hailu Luo,Shuangchun Wen,Zhaowei Liu +8 more
TL;DR: A mechanism to realize an optical spatial differentiator consisting of a designed metasurface sandwiched by two orthogonally aligned linear polarizers based on a Pancharatnam–Berry-phase metasURface is demonstrated, showing versatile edge-detection capability with exceptional quality.

Mapping multisensory parietal face and body areas in humans
Ruey-Song Huang,Ching-fu Chen,Alyssa T. Tran,Katie L. Holstein,Martin I. Sereno,Martin I. Sereno,Martin I. Sereno +6 more
TL;DR: The results suggest the parietal face and body areas fuse multisensory information in peripersonal space to guard an individual from head to toe.
Neural Substrates Underlying the Passive Observation and Active Control of Translational Egomotion
TL;DR: Functional magnetic resonance imaging (fMRI) is used to map the neural substrates underlying the passive observation and active control of translational egomotion in humans and suggests that PIVC plays an active role in sensing and guiding translationalEgomotion that moves an observer aside from impending obstacles.

Nanoscale optical pulse limiter enabled by refractory metallic quantum wells
Haoliang Qian,Shilong Li,Yingmin Li,Ching-fu Chen,Wenfan Chen,Steven Edward Bopp,Yeon Ui Lee,Wei Xiong,Zhaowei Liu +8 more
TL;DR: A reflection-mode pulse limiter (sub–100 nm) using nanoscale refractory films made of Al2O3/TiN/Al2O 3 metallic quantum wells (MQWs), which provide large and ultrafast Kerr-type optical nonlinearities due to the quantum size effect of the MQW could find important applications in nanophotonics, nonlinear optics, and meta-optics.

Mapping the complex topological organization of the human parietal face area.
TL;DR: High signal‐to‐noise surface coils are constructed and phase‐encoded air puffs and looming stimuli are used to map topological organization of the parietal face area at higher resolution to identify a region extending between the superior postcentral sulcus and the upper bank of the anterior intraparietal sulcus.
